To simulate a new economical architecture for PEM fuel cell and investigate the effectiveness of the introduced structure on the performance, computational fluid dynamics (CFD) code is used to solve the equations for a single domain of the cell namely: the flow field, the mass conservation, the energy conservation, the species transport, and the electric/ionic fields under the assumptions of st...

Fenugreek is one of the important edible and medicinal vegetables that have a long history of cultivation and consumption. Characterize the extent of the genetic diversity among landraces will provide a good context for future breeding programs and genetic resource preservation. Genetic diversity and population structure of 88 individuals of eight landraces of Iranian fenugreek evaluated based ...

The aim of this paper is numerical and experimental study of the effects of flow hydraulics, pipe structure (particularly elastic behaviour) and submerged jet on leak behaviour. In this regard, experimental tests were performed on a high-pressure circulation set up. Experiments were performed on an old steel pipe and a High Density Polyethylene (HDPE) pipe discharged to the atmosphere in a wide...

Myliobatidae is a family of large pelagic rays including cownose, eagle and manta rays. They are extremely efficient swimmers, can cruise at high speeds and can perform turn-on-a-dime maneuvering, making these fishes excellent inspiration for an autonomous underwater vehicle. Myliobatoids have been studied extensively from a biological perspective; however the fluid mechanisms that produce thru...

In an open channel, a hydraulic jump is the rapid transition from superto sub-critical flow associated with strong turbulence and air bubble entrainment in the mixing layer. New experiments were performed at relatively large Reynolds numbers using phase-detection probes. Some new signal analysis provided characteristic air–water time and length scales of the vortical structures advecting the ai...

This is a joint work with Andro Mikelić (University of Lyon 1, France), Josip Tambača (University of Zagreb, Croatia), Giovanna Guidoboni (University of Houston, USA), Dr. Craig Hartley (Baylor College of Medicine, USA), Dr. Doreen Rosenstrauch (Texas Heart Institute and The University of Texas Health Science Center at Houston, USA), and Dr. Z. Krajcer (Texas Heart Institute and St. Luke’s Epis...

In this paper, novel algorithms computing dense 3D scene ow from multiview image sequences are described. A new hierarchical rule-based stereo matching algorithm is presented to estimate the initial disparity map. Di erent available constraints under a multiview camera setup are investigated and then utilized in the proposed motion estimation algorithms. We show two di erent formulations for 3D...

This paper presents a modular and extensible style of language speciication based on meta-computations. This style uses two monads to factor the static and dynamic parts of the speci-cation, thereby staging the speciication and achieving strong binding-time separation. Because metacomputations are deened in terms of monads, they can be constructed modularly and ex-tensibly using monad transform...
